ToaZZ whom it may concern:

Be it known that I, JASPER V. CARSON, a citizen of the United States,residing at Gunwald, in the county of Lucas and State of Iowa, haveinvented a new and useful Oiling System for Automobiles, of which thefollowing is a specification.

The object of my invention is to provide an improved oiling systemespecially adapted for use on a well known make of popular pricedautomobiles; and to prov de two forms of the invention, one of which maybe built into the engine apparatus as it is manufactured; and the otherbeing an accessory adapted to be applied to a completed car. I attainthe objects of my invent on by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a vertical sectlon, partlyin elevation, of the invention bullt into the motor system.

Fig. 12 is an enlarged detail view of parts shown in Fig. 6.

' .Like numerals designate like parts in each of the views.

Referring/to Figs. 1,5 inclusive of theaccompanying drawings ,(andso faras the numeralsv are-applicable, to the remaining views), I provide atank 1 mounted on the to the filling spout 9. In the lower end of V therib 5 is an oil passage 11, with which the oil passage 20 in spindle 17alines when member 17 is in the position shown in F 1g. 2, and in whichposition passages 11 and 20 are both in alinement with the passage orconnection 12 which is in communication with oilsupply pipe 13. Oilsupply pipe 13, disposedasshown in Fig. 2, 1s diS- posed within conduit14, which is of larger diameterand to which it is attached in spacedrelation by a plurality of suitable braces or spacing members 25, asshown-0n an enlarged scale .in Fig. 5, there being any suitablerequirednumber of these memhers for supportlng pipe 14 in spacedrelation to pipe 13. .Theouter pipe 14 is pro vided with perforations15at its upper end, and with perforations 16 at its lower end.

Referringto Fig. 2 ,1 provide a nut 18 attached to the lowerend ofspindle 17. I also provide a suitable spring 19 interposed between nut18 and base 3 of the oil tank 1, whereby -to-normally hold spindle 17 inits lowermost position in which oil passage 20 is alined with .oilpassages 11 and 12. Perforations 15 at the upper end of the outer pipe14 are for the admission of air into the upper .end of theclosed pipe l;while perforations 16 at the lower end of pipe 14 are for the admissionof oil to that element.

Referring to Figs. 3 and .4; I provide an opening 21in the upper end oftank 5 alined withoilfilling passage v22 of the filling arm 8.; throughwhich oil is supplied to tank 1. I prefer to provideasuitable recess 23in the casing of tankl, in which recess is mounted ,a suitable glass oilgage 24 for vdeterminlng the quantity of oil in' the tank by aninspection ofthe gage 24. Tank 1 is of semi-cylindrical shape as shownin Figs. 3 and it, and iscast integral with the fly-wheel covering. Theplate l3 and a suitable ,gasket interposed between the portion of platethatengages casting 2 provides the airtight closure fortheoil tank 1 ofwhich it is the base. Tank 1 extends up to the bottom of the coil boxand is of the same width and thickness except for the recess for theglass gage. Tank 1 is to be rounded on the upper corners and edges,preferably. It will hold about three quarts of oil. It is slightlyconcaved on the front side to accommodate the end of the motor. Asuitable indentation 7 for the reception of filling spout 8 is providedas shown in Fig. 3, and from which seat the spout may be swung to theposition shown in dotted lines in Fig. 3, for convenience in filling thetank, the filling spout being pivotally or swingably mounted at one endas shown. As indicated in Figs. 2 and 3, cap 10 is provided with a smallopening or perforation to permit of the escape of air.

Referring to Fig. 2 the coil spring 19 normally holds spindle 17 snuglyseated in the position shown in Fig. 2, with passages 11 and 20 alined,and the spout 8 is seated in indentation 7 flush with the tank. Whenfilling spout 8 is swung outwardly, for purpose of filling, to theposition shown in Fig. 1 and in dotted lines in Fig. 3, the lower end ofthe spout alined with opening 21 in the upper end of the tank and theopening 20 in the lower end of spindle 17 is moved out of alinement withpassa e 11 to prevent oil fiowing'into pipe 13. ipe 13 which is attachedto the connection 12 by a suitable watertight connection, extends downto the a bottom of the transmission case to a point midway up and downbetween the two pet cocks on the outside of the transmission case, butwith the lower end in the center thereof. This pipe 13 (and spaced pipe14) hangs just behind the flywheel and in front of the transmissionbands, and bends around the transmission ears in reaching the bottom ofthe case. Fipe 14 is preferably fastened by a collar or braces 25 to thesmaller pipe 13 and extends to the extreme bottom of the transmissioncase and is open at the bottom. It is also perforated with 4; inchopenings 16 up to almost the level of the pipe 13 which it incases. Gage24 is suitably connected with the interior of tank 1 to permit the oilto flow freely into the gage, which is mounted in the customary manner.WVhen oil is consumed to a point where its level falls below the end ofthe small pipe 13, air is admitted through the perforations 15 at thetop of the largest surrounding pipe 14, and the air flows upward throughpipe 13 in bubbles to the tank above which releases the oil until itreaches a level just above the lower end of the inner pipe 13. The oilis thus kept at a uniform level in the transmission case at all timesregardless of unevenness of roads or other conditions. This is anextremely important factor in the operation of the popular car to whichthis invention is particularly adapted, as too much oil overheats themotor and fouls and breaks the spark plugs, reduces power, and promotesthe formation of carbon in the motor rapidly; while on the other extremea too small amount of oil sup ly is more disastrous and expensive. l/ yinvention will give the numerous owners of this type of car absolutefreedom from one of the most annoying cares, for one filling of the tankwill be sufficient for 400 or 500 miles without further attention.

' Referring to Figs. 6-12, in connection with the details of members 13and 14 shown in Figs. 1 and 2 there is disclosed a modified form of myinvention adapted to be applied as an accessory to the hereinbeforedescribed type of car without any essential modification of itsstructure as now turned out by the factory which built the car. In thisform of the invention I provide a tank 26 which is placed on the leftside of the motor under the hood, the tank being made of heavy glass orother suitable material so that the driver may glance at the tank anddetermine conveniently when it needs refilling, it being merelynecessary to lift the hood. The mouth of the tank 26 is secured by splitcollars 28 which are fastened by suitable bolts to castings 27. Iprovide a spindle 29, nut 34 attached to the end of said spindle in anysuitable manner as by split pin 35, and a coil spring 32 interposedbetween the nut 34 and the end of casting 27 as shown in Fig. 6, andoperating substantially in the same manner as the coil spring, nut andspindle disclosed in the first form of my invention shown in Figs. 1-5.Spindle 29 is provided with oil passage 36 shaped to aline with oilpassage 37 through casting 27 when the tank 26 is in the position shownin Fig. 6. Casting 27 as shown in Fig. 8, is provided with a funnel 39,the small end of which is of suitable size toaline with the opening 36of spindle 29 when the tank 26 is swung to reverse position shown indotted lines in Fig. 7, in which position oil may be poured into tank26. A suitable collar 31 is provided for coil sprin 32 to abut againstas shown in Fig. 6. Spindle 29 preferably is provided with a threadedend 33, as shown. Funnel 39 and its opening 38 are cast integral withmember 27, as shown in Fig. 8.

Referring to Fig. 10, I provide suitable members 41 and 45, the functionof which is equivalent to that of the transmission covering of theautomobile. This frame is protank 26 is nprmally held in upri htposition, but may be readily released an reversed to inverted positionfor purposes of filling. Collar 31 and spindle 29, as shown in Fig. 12,is provided with flanges 49 which set into recesses 50 in casting 27,for stabilizing the container. Collar 31 is provided with longitudinalslots 51 into which a pin 52 projects and in which slots it is slidable.Spindle 29 has a wedge shaped top, as indicated in Fig. 7, against whichthe sides of the brackets 30 fit, holding the spindle part always inrighted position. This edge portion of the spindle is on that part onlywhich fits into the supporting brackets 30, the clamps of which bracketare drawn up tightly and bolted together, as shown in Fig. 6. Spindle 29is about eight inches long and sets level horizontally. About fiveinches of this spindle is tapering at the front end, preferably fromabout one and one-half inches down to about one-half inch at the frontend, to which the coil spring 32 is mounted. Cover 31 is provided with aflange that points outward and backward.

The same operation occurs with this form of the invention when fillingas in the form first described, in regard to the openings for thepassage of oil being thrown into and out of alinement at appropriatetimes for admitting or preventing the passage of oil to and from thetank. The tank holds about two and one-half quarts preferably. Theoperation of pipes 13 and 1a is identical with that described in thefirst part of this specification relating to Figs. 1-5.

hat I claim is:

1. In a device of the class described, the combination of an oil tankhaving an elliptical mouth, an opposed funnel member, in one of thefunnels of which the mouth of the oil tank is mounted, said funnelmember or inverted position, means for mounting the aforesaid member, aninner oil pipe in communication with the oil passage in the aforesaidspindle, the oil pipe extending into the lower portion of the crank caseof the automobile, and a concentric outer pipe mounted on the firstmentioned pipe, said second pipe having its lower end extendingsubstantially below the end of the inner pipe and being in communicationwith the oil in the crankcase of the automobile and having perforationsin its upper end for the admission of air, and means for gaining accessto said pipes.

2. In a device of the class described, the combination of an invertibleoil tank, a spindle on which the oil tank is pivotally mounted, saidspindle having an oil passage in communication with the oil tank, an oilconduit from said oil passage extending into the lower portion of thecrankcase of the automobile, and a concentric outer conduit mounted onthe first mentioned conduit, said second conduit having its lower endextending substantially below the end of the inner conduit and being incommunication with the oil in the crankcase of the automobile and havingperforations in its upper end for the admission of air.
